GRUBBING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 650,265, dated May 22,1900.

Application filed August 1, 1899.

To all whom it may concern/.-

Beit known that I, GEORGE R. MoOHEsNEY, of the city of New York, boroughof Manhattan, in the county and State of New York, have invented anewand Improved Grubbing- Machine, of which the followingis a full, clear,and exact description.

This invention relates to a grubbing-machine of that class in which ahand-lever is provided and fulcrumed on a block to which is attached agrubbing-arm, so that when the lever is thrown the grub is clampedbetween the arm and the lever, and by these means the grub is drawn. Inthis class of devices great trouble has been experienced in properlyconstructing the lever so as to prevent the breakage thereof and also inarranging the parts so that the grub is properly grasped and drawn outof the ground without snapping or breaking the grub.

My invention seeks toovercome these disadvantages by providing improvedmeans for strengthening the lever and also by insuring the properengagement between the lever and grubbing-arm.

This specification is the disclosure of one form of my invention, whilethe claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective view of the in- Vention employed in connectionwith a large grub or sapling. Fig. 2 is a section taken through theupper portion of the strengthening devices. Fig. 3 is a section takenthrough the fulcrum of the lever. Fig. 4 is a section taken through theshort end or nose of the lever, and Fig. 5 is a fragmentary Viewillustrating the use of the apparatus in connection with a small grub.

The grubbing-lever 6 is supported on a foot-block 7 by means of twostandards 8 and 9, which are fastened rigidly to the block and whichcarry a bolt 10, forming the fulcrum of the lever. The standard 9 isextended Serial No. 725,736. (No model.)

best in Fig. 1, and being bifurcated to form claws 14:, the purpose ofwhich will hereinafter appear.

, I The grub-lever is provided with a strengthare held fast to the leverby means of a clip 17, which embraces the lever and side plates andholds the parts securely without the necessity of boring through thelever, and thus reducing the strength thereof. The bolt 10 is passedthrough the side plates 15, as shown best in Fig. 3, and at this bolt isthe only point at which the lever is bored. At the nose of the lever thestrengthening-strap, composed of the side plates 15 and cross or nosepiece 16, is held by means of a saddlestrap 18. This strap is U-shapedin form, as best shown in Fig. 4, and is saddled onto the nose or frontend of the plate, the strap 18 lying inside of the side plates 15 of thestrengthening-strap. The lower extremities of the sides of thesaddle-strap 18 are bent outward and upward to form hooks 19, whichhooks respectively receive the lower edges of the front ends of the sideplates 15. In order to make a snug fit between the several parts, thelever may be reduced at its nose, so that the saddle-plate 18 may be letinto the reduced portion, and thus lie flush with the main portions ofthe lever. The Width of the side plates 15 of the strengthening-strapmay be made less than the width of the lever, as is indicated in thedrawings, so that should the lever shrink the clip 17 may be tightened,

thus accounting for the shrinkage of the lever.-

With this construction, assuming that the grubbing-machine is employedas shown in Figs. 1 and 5, the nose of the lever is engaged with thegrub, and the hook 12 of the grubbing-arm is caused to embrace the grub,as shown, the block 7 being tilted in the manner indicated. Now bydrawing down on the rear or free end of the lever the lever is throwninto practically a horizontal position and the nose of the leverelevated, thus drawing the grub. It will be observed that the strain ofthe grub on the lever is transmitted directly to the cross or nose piece16 of .the strengthening-strap, and this by transmitting the strain tothe front ends of the side plates 15 causes the saddle-plate 18 to takethe major portion of the strain,

saddle-strap bearing on the lever, as shown,ef-

fectually transmits the strain to the leverand produces the strongestpossible construction without the necessity of bolt-holes through thelever, which would reduce the strength 2; thereof. It may further beobserved that the strain of the grub bearing down-011 the'front; ends ofthe side filates 15 will tend to throwup-the'rear endsof the side platesand that this strain is'counteracted by the clips 17. ;Fig.

1 shows the grabbing-machine used in connection with a large orWell-grown grubor sapling, while Fig. 5 illustrates it in use in In thislatter view itlS shownthat the levermovestoward'f connection with asmall grub.

Now this and minor details of my-iriventionafiay be resorted to withoutdeparting. from the spirit and scope thereof. Hence I consider myselfentitled to all such variations as may lie within the scope of myclaims; Having thus described my invention, I claim as new and desire'to claini by Letters Patent-o y 1'1.
